Configuring Performance Parameters 3 The data path consists of the source port of the switch or director being configured, the exit port of that switch or director, and the domain ID of the destination switch or director. Each switch or director must be configured for its part of the desired path in order to achieve optimal performance. You may need to configure Preferred Paths for all switches or directors along the desired path for a proper multi-hop Preferred Path. (For examples of Preferred Path implementation and other related information, see your product's Element Manager manual.) The following rules apply when configuring Preferred Paths: • The switch's domain ID must be set to insistent. • Domain IDs must be in the range of 1 through 31. • The specified numbers for source ports and exit ports must be in the range equal to the number of ports for the switch being configured. • For any source port, only one path may be defined to each destination domain ID. Use the following procedure to configure preferred paths: 1. Select Configure > Performance > Preferred Path on the navigation panel. The Preferred Path configuration page (Figure 3-14) displays. 3-28 EFCM Basic User Manual
